Here's the original page for the vacuum trick. He doesn't necessarily mention NOx as something that'll lower. Emissions Trick I'm actually in the same boat, but I'm failing on CO, and not NOx. I've been through the testing station 5 times so far, changing items like Cats, o2's, etc, etc. I'm going through tonight after work using the trick.
